Before you read this make sure that you have a transfer cable or a flash drive.

Ok so the first thing that you will need for modded zombies is MODIO you can download that file here [ Register or Signin to view external links. ]

Next you will need to download a modded GPD you can find tons of them on forums on TTG but heres the one I use... [ Register or Signin to view external links. ]

After you do that follow these steps...

1. When in modio dont click replace file click inject file into current folder.

2. rehash and resign (Obviously)

3. When loading up black ops make sure your signed out of any accounts

4. also make sure your ethernet is unplugged.

5. when your at the main menu sign in to your modded profile offline.

6. go to zombies and start a solo game. (The mods will now work)

7. plug your ethernet back in and connect to xbox live.

8. end the solo game go private match and have fun.

If this helped you plz thanks the topic.
